Continuum modeling of radiation defects and mechanical properties

I am modeling irradiated zirconium using ABAQUS

I am looking for a UMAT that has the HCP stucture in it (slip systems....)

Besides I need to incorporate the damage inside my model (UMAT FILE)

and then I will do indentation on my sample to get mechanical properties.

If anyone has ideas or even any UMAT that is related to damage or HCP structure, I would appreciate his help

Thanks

Elias
